Electrical data for inputs and outputs
Note
• An additional document with Ex safety instructions is
available for measuring systems that are used in
potentially explosive atmospheres.
• Ex safety instructions are an integral part of this manual.
As a result, it is crucial that the installation guidelines and
connection values it lists are also observed. The icon on
the name plate indicates the following:
Current output Uco / 32, 31 / 32
Can be configured for outputting mass flow and volume
flow via the on-site software.
Power supply
*Source voltage U depends on the load R
B
and must be within the
permissible range.
For information on communication via the HART protocol,
refer to HART® communication on page 48.
